Aerial Reconnaissance In World War II
A transformational growth in aerial reconnaissance occurred in the years 1939–45, especially in Britain and then in the United States. It was an expansion determined mostly by trial and error, represented mostly by new tactics, new procedures, and new technology, though rarely by specialized aircraft types. The mission type branched out into many sub-types, including new electronic forms of reconnaissance. In sharp contrast with the case during the pre-war years, by 1945 air reconnaissance was widely recognized as a vital, indispensable component of air power. Pre-war situation In the interwar years, reconnaissance languished as a mission type and tended to be overshadowed by routine aerial mapping. This was despite the growth (in the United States and Britain) of a doctrine of strategic bombardment as the decisive weapon of war. Experience would soon prove that bombing was completely ineffective unless accompanied by intensive aerial reconnaissance. In the 1930s, gradual technic ...

Spitfire Mk11 Pl965 Arp
The Supermarine Spitfire is a British single-seat fighter aircraft used by the Royal Air Force and other Allied countries before, during, and after World War II. Many variants of the Spitfire were built, from the Mk 1 to the Rolls-Royce Griffon engined Mk 24 using several wing configurations and guns. It was the only British fighter produced continuously throughout the war. The Spitfire remains popular among enthusiasts; around 70 remain airworthy, and many more are static exhibits in aviation museums throughout the world. The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works, which operated as a subsidiary of Vickers-Armstrong from 1928. Mitchell developed the Spitfire's distinctive elliptical wing with innovative sunken rivets (designed by Beverley Shenstone) to have the thinnest possible cross-section, achieving a potential top speed greater than that of several contemporary f ...

Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that can ...

Topographic Map
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and artificial features. A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map projection, coordinate system, ellipsoid and geodetic datum. Official topographic maps also adopt a national grid referencing system. Natural Resources Canada provides this description of topographic maps: Other authors define topographic maps by contrasting them with ano ...

Second Italo-Ethiopian War
The Second Italo-Ethiopian War, also referred to as the Second Italo-Abyssinian War, was a war of aggression which was fought between Fascist Italy (1922–1943), Italy and Ethiopian Empire, Ethiopia from October 1935 to February 1937. In Ethiopia it is often referred to simply as the Italian Invasion ( am, ጣልያን ወረራ), and in Italy as the Ethiopian War ( it, Guerra d'Etiopia). It is seen as an example of the expansionist policy that characterized the Axis powers and the ineffectiveness of the League of Nations before the outbreak of the Second World War. On 3 October 1935, two hundred thousand soldiers of the Italian Army commanded by Marshal Emilio De Bono attacked from Italian Eritrea, Eritrea (then an Italian colonial possession) without prior declaration of war. At the same time a minor force under General Rodolfo Graziani attacked from Italian Somalia. On 6 October, Adwa was conquered, a symbolic place for the Italian army because of the defeat at the Battle of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antoine De Saint-Exupéry
Antoine Marie Jean-Baptiste Roger, comte de Saint-Exupéry, simply known as Antoine de Saint-Exupéry (, , ; 29 June 1900 – 31 July 1944), was a French writer, poet, aristocrat, journalist and pioneering aviator. He became a laureate of several of France's highest literary awards and also won the United States National Book Award. He is best remembered for his novella '' The Little Prince'' (''Le Petit Prince'') and for his lyrical aviation writings, including '' Wind, Sand and Stars'' and '' Night Flight''. Saint-Exupéry was a successful commercial pilot before World War II, working airmail routes in Europe, Africa, and South America. He joined the French Air Force at the start of the war, flying reconnaissance missions until France's armistice with Germany in 1940. After being demobilised by the French Air Force, he travelled to the United States to help persuade its government to enter the war against Nazi Germany. Saint-Exupéry spent 28 months in America, during w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bloch 174
The Bloch MB.170 and its derivatives were French reconnaissance bombers designed and built shortly before the Second World War. They were the best aircraft of this type available to the at the outbreak of the war, with speed, altitude and manoeuvrability that allowed them to evade interception by the German fighters. Although the aircraft could have been in service by 1937, debate over what role to give the aircraft delayed deliveries until 1940. Too few in number to affect the Battle of France, they continued in service with the Vichy forces after the armistice. The MB.174 is notable as the aircraft flown by Antoine de Saint-Exupéry, author of '' The Little Prince'' during the campaign. His work (''Flight to Arras''), published in 1942, is based on a 1940 reconnaissance mission in this type of aircraft. Design and development In 1936, the Ministry for the Air initiated a programme of modernisation of French aviation which included a request concerning a two- or three- ...

Potez 630
The Potez 630 and its derivatives were a family of twin-engined, multirole aircraft developed for the French Air Force in the late 1930s. The design was a contemporary of the British Bristol Blenheim (which was larger and designed purely as a bomber) and the German Messerschmitt Bf 110 (which was designed purely as a fighter). The Potez 630 was in use by several operators during the Second World War. Following the Battle of France, both the Vichy French Air Force and Free French Air Forces used the type; a number of captured aircraft were operated by several air wings of the Axis powers. After the end of the conflict in 1945, a handful of aircraft were used for training purposes for some time. Development Origins On 31 October 1934, the French Ministry of Air issued a specification for a heavy fighter. The specification demanded the aircraft be capable of performing three principal roles: fighter direction, in which it was required to lead formations of single-engine fight ...
